Radioactive decay is the strange and almost mystical ability for one element to naturally and spontaneously transmute into another. In the process, those elements tend to emit deadly forms of ...

The discovery of radioactivity allowed scientists to develop new methods of determining Earth's age, with astonishing results. Our planet is far older than people had thought! Students can understand ...

In this lesson, students will simulate the randomness of decay in radioactive atoms and visualize the half-life of a sample radioactive element. This lesson can be completed in two (2) 45-minute class ...
